Color Shift

COLOR SHIFT

  • Aging UV exposure may cause plastics to change color
  • Operating conditions and contaminants in the atmosphere may cause color changes

MACADAM ELLIPSE

  • Defines the color point specification of lamps
  • Guidelines for how a person can distinguish between similar colors
  • 2 step ellipse: 2 times the just noticeable difference in color

BINING

  • Measure the output of the LEDs AND sort them into various ranges, or bins, before sale, based on color and flux
  • Size and range of colors of the bins is critical to determine how close a match the LEDs will have to each other and the color variation between units
  • All supplied LEDs must fall within a 2 step macadam ellipse [lm-79 and lm-80 of IESNA]

COLOR RENDERING INDEX

  • Measure of color fidelity
  • Does not account for object color shifts that increase color saturation which can enhance visual preferences, color discrimination ability and visual clarity

COLOR QUALITY SCALE

  • Being developed by the national institute of standards and technology to be considered for the TC 1-69
  • Ability to account for the direction of object color shifts
  • Represents the overall color quality of products for all types of light sources

Defining Shadows and Darkness

“It is necessary to return to the point where the interplay of light and dark reveals forms, and in this way to bring richness back into architectural space. Yet, the richness and depth of darkness has disappeared from our consciousness, and the subtle nuances that light and darkness engender, their spatial resonance – these are almost forgotten. Today, when all is cast in homogenous light, I am committed to pursuing the interrelationship of light and darkness . Light, whose beauty within darkness is as of jewels that one might cup in one’s hands; light that, hollowing out darkness and piercing our bodies, blows life into ‘place’.”

– Tadao Ando (1990)

Impact of Temperature on Light

When fixtures and lighting systems are tested under the IEC 60598, the ambient temperature is kept close to 25 degree centigrade and 65% relative humidity. After injecting the right voltage, the fixture is kept burning for four hours. In this time the temperature rise of the various components used in the fitting would have stabilized, and the temperature rise recorded through the help of thermocouples fixed to the various parts of the fitting. From this set of data, the release of the fitting is decided.  If the fitting is found suitable for 25 deg. Ambient (Outdoor) and 35Deg. Ambient for indoor, it is cleared for sale, as the temperature in Europe never exceeds these temperatures. However, in other parts of the world, the temperatures are usually much higher.

  • Fixtures are currently tested between 20°c and 30°c which is not adequate.
  • Under the IEC 60598 [25°c, 65% RH], the fixture is lit for four hours until the temperature is stabilized.
  • If the fitting is found suitable for 25°c [outdoor] and 35°c [indoor] conditions, it is cleared for sale.
  • Europe rarely exceeds these conditions but other parts of the world do.

Impact of Humidity on Light

Some areas have almost 90% humidity through several months of the year. The humidity in the air coupled with water in the ground means that all components of a lighting system need to be addressed as a complete system to ensure proper functioning. The water/ humidity finds the weakest link in the system and creeps through to the other parts via capillary action which has an adverse impact on the functioning and life of the components.

Choice of hardware must also be informed by whether the environment is near the ocean, as the salines will then have an adverse impact on the componentry.

  • Water finds the weakest link in the system and seeps through via capillary action
  • Alia Diwa Resort Goa:
    • Wiring processes: use of glands, mastic tapes and silicone fills essential to keep humidity and ground water out
    • Salinity has an adverse impact on the componentry.
